Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth. These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes.

The lithology of this body of sediment is characterized by the dominance of sandstones (also known as arenites) and fluvial gravel, of siliceous nature. Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth. These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes. The complicated sedimentarian architecture of the layers where most large vertebrates are found makes the excavation methodology a real challenge. Sometimes the local miners have to excavate long tunnels that follow the distribution of the fossiliferous layer.\u003cbr\u003e\u003cbr\u003eThe pterosaurs dentition rests in the Upper Cretaceous in North Africa are relatively common among the fauna which got preserved from those ecosystems around 100 million years ago. However, only two different pterosaur taxons have been described. Mader \u0026amp; Kellner (1999) (Full reference: B. J. Mader and A. W. A. Kellner. 1999. A new anhanguerid pterosaur from the Cretaceous of Morocco. Boletim do Museu Nacional - Geologia 45:1-11) described the Coloborhynchus moroccensis species, belonging to the Anhangueridae family, which lived at the middle of the Cretaceous (between the Albian and Cenomanian stages, about 105 million years ago). Remains have been discovered in Morocco. Another alternative combination in the nomenclature of this taxon is Siroccopteryx moroccensis.\u003cbr\u003e\u003cbr\u003ePhylogeny: The descriptors of \u003cem\u003eSiroccopteryx\u003c\/em\u003e placed this genus in the family Anhangueridae, sensu Kellner. David Unwin, however, indicated in 2001 that it was a species of \u003cem\u003eColoborhynchus\u003c\/em\u003e, then he called it as C. moroccensis and being a member of the Ornithocheiridae. This has been controversial. In the same year, Michael Festnacht suggested it was more similar to \u003cem\u003eAnhanguera\u003c\/em\u003e due to the wide end of the snout. In 2009, Kellner considered that \u003cem\u003eSiroccopteryx\u003c\/em\u003e, \u003cem\u003eColoborhynchus\u003c\/em\u003e clavirostris and Uktenadactylus probably formed together a clade within Anhangueridae.

The lithology of this body of sediment is characterized by the dominance of sandstones (also known as arenites) and fluvial gravel, of siliceous nature. Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth. These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes. The complicated sedimentarian architecture of the layers where most large vertebrates are found makes the excavation methodology a real challenge. Sometimes the local miners have to excavate long tunnels that follow the distribution of the fossiliferous layer.\u003cbr\u003e\u003cbr\u003eThe pterosaurs dentition rests in the Upper Cretaceous in North Africa are relatively common among the fauna which got preserved from those ecosystems around 100 million years ago.
